Smoke detector FW2-SMK
It is a two way wireless photoelectric smoke & heat detector using low current technology.
The detector automatically compensates for long-term environmentally induced changes to maintain a constant smoke sensitivity. When the drift compensation has reached its high or low limit of adjustment, the detector will go into the trouble state.
The heat detector will go into alarm when the heat signal level exceeds the heat alarm threshold and will automatically restore when the heat signal level falls below the heat alarm threshold.
